Quick answer
Choose a speedring that matches your strobe's mount type — Bowens, Elinchrom, Photogenic, or a proprietary Westcott mount — and confirm the modifier's attachment style (pin-mount or speedring-mount).
Bowens vs. Elinchrom vs. proprietary mounts
Bowens mount is the most common standard among studio strobes, used by brands like Godox, Flashpoint, Calumet, and Westcott's FJ series. A Bowens speedring gives you the widest choice of modifiers because most softbox manufacturers design for this mount.
Elinchrom uses a different bayonet-style mount with three prongs. If you own Elinchrom lights (including the Prolinca line), you need an Elinchrom-specific speedring. The trade-off is a smaller pool of compatible modifiers, but the mount itself is very secure.
Westcott's FJ800, FJ400 II, FJ400, and FJ250 strobes use a Bowens mount natively, so a standard Bowens speedring works. However, if you own a Rapid Box Switch or Beauty Dish Switch modifier, you need the Switch Insert (Bowens) to attach it to those lights.
Photogenic strobes have their own mount design. The Switch Insert (Photogenic) lets you use Rapid Box Switch modifiers with Photogenic lights, but you cannot use a standard Bowens speedring with a Photogenic strobe.
Switch Insert (Photogenic)
Speedring vs. Switch Insert: what's the difference?
A traditional speedring connects a softbox directly to the strobe using a metal ring with mounting pins or a bayonet. It is the universal adapter for most softboxes.
A Switch Insert is a smaller adapter designed specifically for Westcott's Rapid Box Switch and Beauty Dish Switch modifiers. It pairs the modifier's quick-release mechanism with your strobe's mount. If you already own a Rapid Box Switch, you need the correct Switch Insert — not a full speedring.
Decision rules for picking your speedring
- Identify your strobe mount: Check the back or side of your strobe for the mount type: Bowens (three prongs with a locking ring), Elinchrom (three prongs with a bayonet twist), or proprietary (e.g., Photogenic's unique shape). If you are unsure, look up your strobe model online or measure the mount opening diameter.
- Match the speedring to the mount: For Bowens-mount strobes, choose a Bowens speedring. For Elinchrom, choose an Elinchrom speedring. For Photogenic, use a Photogenic Switch Insert if you own a Rapid Box Switch modifier. Do not assume a speedring fits all strobes — mount compatibility is non-negotiable.
- Consider your modifier type: If you own a standard softbox with a speedring, buy a standalone speedring. If you own a Westcott Rapid Box Switch or Beauty Dish Switch, buy the corresponding Switch Insert instead. Switch Inserts are smaller and cheaper than full speedrings, but they only work with Switch-series modifiers.

Who should buy which speedring?
Best for
- Photographers with Bowens-mount strobes (Godox, Flashpoint, Westcott FJ series, Calumet) who want maximum modifier compatibility.
- Elinchrom strobe owners who need a secure, dedicated speedring without adapters.
Not for
- Photographers using Photogenic strobes with standard softboxes — you need a Photogenic-specific speedring, not a Bowens or Elinchrom model.
- Owners of Westcott Rapid Box Switch modifiers who already have the correct Switch Insert — buying a full speedring adds unnecessary cost and complexity.
